 The M880/890 trucks were adopted as part of a drive by the U.S. military to use commercial off-the-shelf (COTS) vehicles, with appropriate modifications, where such usage was feasible.An armored variant was built by Cadillac Gage as the Ranger.For almost a decade the Dodges were referred to as "880", "890", or most commonly called "five-quarters"; (the term "CUCV" did not appear until the 1980s when GM was contracted to replace the M880/890 trucks).
